The Dynon GPS antenna is more than antenna, it's the whole GPS processor. It outputs digital, RS-232 data, not RF. You can split the output of this up to 3 times if you need to, but this is at a non-standard speed to support the 5Hz output rate. You can also ask SkyView to echo the output of this at any speed you want.
No devices that use RF signals can split their antennas.
